. Burners, of which the following is a specification.

This invention relates to improvements in hydro carbon burners, particularly adapted, though not necessarily'limited in its use for burning kerosene, and one of the objects of the-same is to provide a burner of this type,

which will be simple, durable and compact in construction, and effective and eflicient in operation, and one which will economically burn kerosene with a blue flame which gives no odor.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed, and shown in the accompanying drawings illustrating the invention, and in which- Figure 1 is a vertical longitudinal sectional view of an improved burner of this type constructed in accordance with the principles of this invention.

Referring more particularly to the drawings, thenumeral 10 designates generally a vaporizing chamber which is preferably circular in cross section and is of a width somewhat greater than the height thereof, so as to form a flattened chamber. This chamber-is preferably annular in construction to" form an opening of somesize through. the

center thereof, and which opening is out of communication with the chamber. Encom- Specification of Letters Patent.

chamber 10, an

passing the opening thus formed is a wall, the portion 11 of which projects on one side of the chamber in the form of an annular flange, and the portion 12 projects on the opposite side of the chamber, and depends for some distance below the lower face of the chamber. This flange 12 is provided with a series of lateral openings projecting therethrough ad'acent the lower face of the the chamber 10 is preferably reduced in size as at 14 to form a pocket 15 surrounding the flange l2 and in which pocket the flame enters as it passes through the openings 13, so as to impinge on the bottom of the chamber to heat the latter. These flanges 11 and 12 forming a wall around the opening may be of any desired length, and the upper portion of the wall thus formed is flared outwardly as at 16 for a purpose to be hereinafter described.

pipe 18 which leads from a tank 19, lo-

cated in such position with respect to the chamber 10 that the oil will be fed by grav-' ity to the chamber 10. A controlling valve 20 is provided in the pipe 18 for controlling the supply of oil to the chamber.

Arranged within the wall formed by the flanges 11, 12 is another chamber 21, which is of a size somewhat smaller than the diameter of the opening to form a flame passage 22 between the wall of the chamber 21 and .the wall surrounding the opening. This chamber 21 is provided preferably with a flange 23 projecting thereabove, and which flange preferably extends above the flange portion 11 of the 'wall, and is itself flared outwardly from the chamber 21, to cooperate with the flared portion 16 to direct the flame away from the chamber 21, and to spread the flame. The chamber 21 is preferably held in, position by means of a pipe2 l which is connected with the chamber 21 to communicate therewith and forms an inlet for the vapor from the chamber 10 into the chamber 21, this pipe 24 being also connected to the outlet 25 of the chamber 10.

Leading from the chamber 21 is an out let pipe 27, which conducts the vapor from the chamber 21 to a pipe 27 which is arran ed below both of the chambers, to extend transversely with respect tothe opening in the chamber 10, which is surrounded by the wall, and this pipe 27 is provided with a jet opening 28 arranged directly below the bottom 29 of the chamber 21 so as to direct the flame into the space surrounded by the flange portion 12 of the wall and against the bottom of the chamber 21. Th1s bottom 29 of the chamber is preferably arched or curved upwardly as shown and stands above the openings 13 in the wall surrounding the opening in the chamber 10, and serves as a means for directing the 1mpinging flame through the openings 13 so that theflame will strike the bottom of the chamber 10. At the same time a portion of the flame will pass through the flame passage 22 to encompass the chamber21, heat-- ing the latter to a high temperature, and the flame will'also be directed to portions of the pipes 24, 26.

In order to assist in further heating the pipe 26, the latter may if desired be arranged so that it will pass through a portion of the chamber 10, and a controlling valve 31 is arranged in the pipe 26 for con trolling the supply of vapor to the jet openus it will be manifest that when the chamber and discharged at a higher temperature prevents the formation of carbon in the vapor generator, due to the high temperature which is obtained, and when the vapor flows from the chamber 10 into the chamber 21, it will be' heated to a very high degree, and the super heating of the pipes 24, 26 prevents any possible condensation, so that the vapor will be discharged in a perfectly dry condition through the jet opening 28. By the aid of this super heat ing and'a supply of suflicient air a blue flame is produced which has no odor.

In order to facilitate the formation of the chambers 10 and 21, the former is provided with plug openings 32 which may be closed by suitable plugs 33 and the chamber 21 is provided with plug openings which may be closed by suitable plugs 34. The burner thus formed is adapted for any stoves, either for large or small stoves, or for boiler or furnace use and may be supported in any desired manner preferably by means of a supporting frame or construction of any desired configuration, the frame preferably being formed of angle pieces 35 having walls 36 secured thereto and a closed the supporting structure and the pipe 27 will also extend into the interior of the structure, preferably by passing through a suitable opening in one of the walls in the structure. In order that the valve device 31 which controls the supply of vapor to the jet opening 28 may be manipulated from the front, it is provided with a long handle which extends toward the front of the structure and preferably terminates in close proximity to the valve device 20. I

In order that the supply of air to the jet opening, which is necessary to support comr bustion, may be controlled, some of the walls with air openings or passages 40 and a .closure 41 which is itself provided with apertures adapted to be brought into and out of register with the openings 40, is provided for each series of theseopenings and may be manipulated by means of handles 42 connected therewith. v

To initially heat the vaporizing chamber 10 and the chamber 21 to start the burner, there is provided an initial heating device or what is sometimes called a priming cup, which is preferably in the shape of a tray 43 having concentric chambers 44-45 spaced from each other to form an air passage of some size therebetween and which air passage encompasses the chainber 45. The chambers are connected preferably by means of ribs 47 extending across the air'passage 46 and these ribs sages or openings 48 which form communication between the chambers'44, 45 so that when the supply of oil is fed to the chamber 45 it will flow through the passages 48 and into the chamber 44. The chamber 45 is preferably provided at its center with an are provided with pasopening 49 of some size through the bottom thereof and a depending and outwardly flared flange is'preferably provided and extends below the bottom of the chamber 45. An upwardly projecting flared flange 51 also surrounds the opening 49 and is preferably of a length to chamber 45. This'flange 51 is preferably extend above the top of the" provided with lateral openings 52 therethrough which form air passages and these openings 52 are arranged in alinement with similar openings 53 in the walls of the chambers 44, 45. Arranged within the chambers and below. these openings is asbestos 54 and tubular members. 55 are secured to and extend through'the bottoms of the chambers 44, 45 to form air passages, and the upper extremities of these tubular members are preferably flared as at 56; The chambers 44, 45 are of such a size and are so arranged that the chamber 45 will be disposed below the chamber 21 while the chamber 44 will stand belowthe chamber 10 to heat the lat ter, and in such a position that when the oil in the chamber 44 is ignited the flame will j flange portion 12 of the wall which extends downwardly from the chamber 10 and enters the flame pocket 15.

The chamber 45 is supplied with oil from the jet opening 28 and in order to prevent the oil from dropping through the opening 49 in the bottom of the chamber 45, a shield 57 is provided which may be adjustably supported by the pipe 27 above the opening 49 so that the oil will be deposited on the shield and will flow therefrom into the chamber 45. This initial heating device or priming cup may be removably supported in any manner, but preferably by means ofhangers 58 in the form of hooks which are of a size and shape to hook over ears or projections 59, which are provided therefor and are preferably arranged in the flange portion 12 of the wall 11, 12. This device is also housed within the supporting structure, and the opening 39 in the top 38 of the structure is of such a size that it will permit this device to be passed into the housing when the chamber 10 is placed in position to rest upon the top of the structure.

-After the chambers 44, 45 havebeen' supplied with oil, the oil may be ignited inany suitable manner, preferably by means of a tube 60 having a handle 61 and a series of apertures 62, the latter being arranged in one end, and suitable material 63 is arranged in the tube adjacent the'apertures for holding oil, so that when the end of the tube is immersed in oil, the oil may be ignited when the tube is withdrawn, and the lighter end of the tube may be passed through a suitable opening in'one of the walls of the supporting structure to ignite the oil in the chambers 44, 45.

In the 1 form of the invention shown in I Figs. 6 and 7, the chamber 21 is dispensed with, and in lieu thereof there is provided a chamber 64, which is formed at the junction of two pipes 65, 66, which latter lead from outlet openings 67, 68 of the" chamber 19, the outlets being preferably opposite each other, so that the pipes 65,66 will be in alinement and the chamber 64 will be disposed in alinement with the opening formed through the chamber 10 and slightly above the top of the wall formed by the flange portions 11, 12.. In this form ofthe invention,

4 the liquid will pass into the chamber 10 through the-pipe 69 which leads from the supply tank and is controlled by a valve 70. The oil-after being heated in the chamber 10 will pass out of the openings 67 68 into the pipes 65, 66 to be discharged into the chamber 64. From this chamber 64 the vapor will flow through a pipe 71, and which.

pipe 71 and the jet opening 73 in the pipe 2 is arranged in a manner similar to the jet opening in the pipe 27.

Arranged above the jet opening 73 and preferably within the opening'surroun'ded by the Wall formed by the flanges 11, 12 is a deflector and spreader 7 which is arched or deflected upwardly as shown, and is of a size somewhat less than the size of the opening in which it is arranged. This deflector is adj ustabl supported preferably by means of a stem 75 having threads thereon and which stem passes.through a threaded core 76 of the chamber 64. Thus it will be manifest that the deflector and spreader 74 may be adjusted toward and away from the jet opening 73 for controlling the flameand for producing the desired kind of a flame. The device is so constructed that when it is adjusted to stand approximately two and one half inches from the jet opening 7 3 a yellow flame will be produced. A distance of ape proximately one and three fourths inches therefrom will produce a white flame while the deflector and spreader when positioned approximately one and one fourth inches from the jet openingwill result in the production of a blue flame which will'burn without odor.

By the provision of the particular form of heating device or priming cup, the chambers may be more readily heated and quicker'results maybe obtained, and by the provision of the second heating chamber into which the vapor is discharged and again heated, the temperature is raised to a very high degree and complete vaporization results,

- and by the arrangements of the pipes which form the conduits or passages through which the vapor flows, in such positions that they will also be impinged upon and heated by the flame, all possibility of condensation is avoided.
